It depends on what turbo it is and hwo much hp you wanna make. If its the holset HX35 it should be good for 350-400hp or so, There are people running them on everything from a 2.3 4l all the way up to 302's. I would say for street it'd be ok boost would build up quick and low, but for 300+ cubes most people run larger turbos. I'm planning on putting one or two on a 273 mopar eventually because they are cheap and I would rather screw up two $100 turbos than two $750 ones. The real problem with holsets is that nobody has compressor maps, so you can't really say yes or no if they are gonna work. For $20 its probably gonna be clapped out too : ) probably for the best that you missed that one. If its an earlier one I don't know much about it.
